source

pub fn new(

 size_y: u16
) -> Self

Creates a new ST7789 driver instance

Arguments

di - a display interface for talking with the display
rst - display hard reset pin
bl - backlight pin
size_x - x axis resolution of the display in pixels
size_y - y axis resolution of the display in pixels

source

pub fn init(
&mut self,
delay_source: &mut impl DelayUs<u32>
) -> Result<(), Error<PinE>>

Runs commands to initialize the display

Arguments

delay_source - mutable reference to a delay provider

source

pub fn hard_reset(
&mut self,
delay_source: &mut impl DelayUs<u32>
) -> Result<(), Error<PinE>>

Performs a hard reset using the RST pin sequence

Arguments

delay_source - mutable reference to a delay provider

source

pub fn set_backlight(
 &mut self,
 state: BacklightState,

source

pub fn orientation(&self) -> Orientation

Returns currently set orientation

source

source

pub fn set_pixel(&mut self, x: u16, y: u16, color: u16) -> Result<(), Error<PinE>>

Sets a pixel color at the given coords.

Arguments

x - x coordinate
y - y coordinate
color - the Rgb565 color value

source

Arguments

offset - scroll offset in pixels

source

pub fn release(self) -> (DI, Option<RST>, Option<BL>)
